How has the writer created an imagery of a flying bird through her words in "A Bird Came Down the Walk—"?

The flying aspect of the bird’s motion comes rather late in Emily Dickinson’s poem. For more than half of the poem, the bird does not fly. Instead, as the speaker observes, he does a number of other actions while on its feet: eating a worm, drinking water from the dew, hopping, glancing around, hurrying, and moving his head. The speaker interprets these actions to mean that the bird feels threatened, so they cautiously extend a crumb. At that point, the flight descriptions and comparisons begin. The only direct reference to a bird flying is the statement “he unrolled his feathers.” The speaker then states that he “rowed . . . Home,” moving through the air more softly and seamlessly than oars in the ocean. A more direct comparison to other creatures’ flight is to butterflies, referring to the ways they “swim,” actually lighting on the water’s surface without making a splash.
